Bundy will play Charlie’s latest sex study research partner, Dr. Jordan Denby. Despite being a brilliant psychologist, her recent divorce, fondness for alcohol and wild mood swings turn the bachelor’s life into an emotional roller coaster.

Bundy is not the only addition to the FX comedy as it undergoes some creative revamping following Blair’s abrupt firing mid-production on the 90-episode Season 2. Brian Austin Green, who previously guest-starred as Sean, the boyfriend of Charlie’s ex-wife Jen (portrayed by Shawnee Smith), was made a regular cast member in June.

Bundy — who recurred on Dixie last season — has appeared on How I Met Your Mother and Guiding Light, and was also nominated for a Tony for her role as Elle Woods in Legally Blonde: The Musical.
